computeMatrixesAndCameras()

void ShadowMatrices::computeMatrixesAndCameras	(	scene::ICameraSceneNode *const	camnode,
		unsigned int	width,
		unsigned int	height
	)

Generate View, Projection, Inverse View, Inverse Projection, ViewProjection and InverseProjection matrixes and matrixes and cameras for the four shadow cascade and RSM.

Parameters

camnode	point of view used
width	of the rendering viewport
height	of the rendering viewport

getTighestFitOrthoProj()

core::matrix4 ShadowMatrices::getTighestFitOrthoProj ( const core::matrix4 &  transform, const std::vector< core::vector3df > &  pointsInside, std::pair< float, float > &  size  )

private

Given a matrix transform and a set of points returns an orthogonal projection matrix that maps coordinates of transformed points between -1 and 1.

Parameters

transform	a transform matrix.
pointsInside	a vector of point in 3d space.
size	returns the size (width, height) of shadowmap coverage
